Mathematics

Answer:

The answer is <u>x=-4</u>

Step-by-step explanation:

3x-5=7x+11

1) you have to move the number that has a variable with it onto one side(3x and +7x) and the numbers that do not have a variable move them onto the other side (-5 and +11),but if you move them you have to change the sign like the underlined numbers below

3x<u>-7x</u>=<u>5</u>+11

2) you have to subtract 3x and-7x which it equals  <u>-4x</u> and then you have to add 5 and 11 which it equals 16

Equation now <u>-4x=16</u>

<u>3)</u> you have to divide -4x into -4x and also divide -4x into 16 which you will get <u>x=-4</u>

Hope it helps out! :)
